To all whom it ma concern: y

Beit known t at ll, WILLIAM D. SKI-D- Monr., a citizen of the UnitedStates, and a resident of Pelham, Westchester' county,

State of New York, have invented certain new and useful Improvements inDumping- Cars, of which the following is a specification.

My invention.. relates to railroad cars, more particularly` to thatclass of cars known as 'dum in cars such as are used for instance, inrailroad construction, for conveying ballast, filling material and thelike to such places as' the same may be needed, and dumping the sameupon or at the side of the right of way; but it will be readilyunderstood that cars constructed yaccording to my invention may be usedfor other purposes as well as'those above specilied.

. The object of my invention is to provide a ca r which shall be sim lein construction -andat the sametimev e cient and easyof operation, andwhich shall be adapted to dump its load either quickly and all at onetime, or slowly vand at a predetermined rate of discharge, and in whichthe adjustment of the mechanism so as to regulate lin the accompanyingdrawings, Figure 1 is a side elevation of the end portion of4 a carconstructed accordingV to my invention. Fig.. 2 is an end elevation ofa` car constructed according to my invention, 'showing the lsame loadedand in its normal erect or carrying position. Fig. 3 is a transversevertical. section through a portion of the car, in its normal position.Fig. 4 is a similar view, certain portions being broken away, showingthecar in its wide open position for dumping at the side of the track. Fig.5 is a transverse vertical section of one side of the car, showing thesame arranged for 'dumping on the track between the wheelsof the car.Figs. 6 and (a are detail views hereafter .further described. Fig. 7 isa detail elevation of the drums upon which the controlling chains arewound. F ig. 8 is a detail viewof the. controlling mechanism. Figs. 9and l0 are respec-,tively front andv side views of the air cylinder.Fig. 1l is a .cross-sectional View through the cylinder. Fig.` 12 isa'detail view of a channel-iron more specifically referred to in thespecification.

v In carrying my invention into effect, ll provide .for the lower partof the car a .running gear of the common or any suitable form ofconstruction, comprising the necessary sills, holsters or analogousmembers,

mounted upon bogie trucks provided with journal-boxes forming thebearings for the ends of the axles, and supported by and secured to therunning gear in any suitable manner are end members 12 and a bottomframe 14.

Referring particularly now to Figs. 3, 4 and 5, it will be seen thatsecurely attached to the end frame members 12 and extendinglongitudinally of the car body oneach side of the car, are ehannel-irons16, to which are secured -members 17, extendin slanting directiondownward and inward. These members 17 are rigidly secured, and

, do'not change their position, but they bear swinging members .19pivotally secured thereto by hinges 18. Extending upward from the bottomframe 14 is a bracket 22, and pivotally attached at 21 to this bracketare swinging members 20.

The parts above described form the carrying bodyT ofthe car, and theyare shown in Fig. 3 in a closed or carrying position, in Fig. 4 in awide open position adapted to deliver the load at the side of the track,and in Fig. 5 in position to deliver the load on the track vbetween thewheels.

When the car body is in the closed or carrying position shown in Fig. 3,the outer edges of the members 20 are supported by legs 28,(diagrammaticallv shown in Figs. fi and 5) pivotally secured thereto bytheir upper ends. rllhe lower ends of the legs 23 bear normally uponrollers 24: journaled in brackets upon a cl1annel-iron 25. Thisconstruction is shown in detail on an enlarged scale in Figs. 6 and 6 3.

ina-

rll`he channel-iron 25 is supported/on wheels 258 which run upon atraclrway 25". 'llhe channel-iron 25 and the track-way 25 are providedwith openings 25 (see Fig. 12) through which the leg 23 may drop downwhen the channel-iron 25 is drawn toward the right of Fig. 6, thusallowing the parts to fall into the position shown in the dotted linesin Fig. 6. Levers 65 areprovided for operating the' channel-irons, shownin Fig..1,. and on an enlarged scale in Figs. 9 and 10. .The member 20is also `supported by the link 2.9,.the lower end of which is pivotallysecured at 28 to the said member nearits outer edge, and the upper endof which. is securedl to the chain 31 which passes over pulleys '35 andVaround drums 37 on the shaft 36..

vThe lower edge of the swinging member y19, when in the closed p ositionshown in Fig. 3, is supported upon the'upper or outer edge of the member20. It is also supported by the link 27, the lower end of `which ispivotally'secured at 2G to th hhhr lhhd thupphhd il i l0 lli@ 'h' ll l lwir@ is pivoh y rauh, il upper endof the member 29 and to the chain 31.It is obvious that the shaft Y36 is rotated so as to wind the chain 31thereonl the links 27 and 29 are drawn up and with them the upper andlower edges respectively' otl the members 20 and 19, as shown in Fig. 3.but when the chain is partially or completely unwound the parts assumethe position of Fig. 5 or 4 as the case may be. v

Pivotally secured' to the frame at 34 is a member 33. When the car is ina position for-dumping at the side of the track the member 33 is placedin the position shown in Fig. 4, but when it is desired to dump on thetrack between the rails the member 33 is placed in the position shown inFig. 5. When the car is in the closed or carrying position the member 33may lie either way. This member 33 is manipulated by hand or in anysuitable manner. 1t will of cour'se be understood that these variousparts above described are duplicated on the two sides of position (asshown in Fig. 4) when the dumping is at theside of the track. Theseresults are obtained bv means of the mechanism now to be described.

Pivotal'lyv attached to the frame of the car,'one on each side, arelevers 70, (see Figs. 2-5) which normally tend to swing down by theirown weight, but which may be secured in theelevated position by catches71 (see Fig. 2). Rigidly secured to these levers, at their inner orpivoted ends, are cross-bars 72, to the ends of which are secured links73 and 74 respectively. The lower one of these links, designated 74, hasits lowerend pivotally secured to an arm or block-176pivotally securedto the ...shortlink 79 which is pivotally secured to a swinging block orstop 80, near one end thereof, the other end of said block 80 beingpivotally secured -at 81 to Vthe frame. It,

will be obvious from anpinspection of Figs. 2, 3, 4 and 5, that when thelever 70 is lowered and the parts are in position shown in Fig. 4, thearm or block 76 bears against the links 27 and 29 and prevents them frombuckling and thereby upholds the swinging 'member 19, but `that whenthelever 70 is' raised and the parts are in the position shown in Fig. 5,the block 80 bears against the joint of the links 27 and 29 and holdsthem in the position shown in' said Fig. 5

The operations of opening the sides of a car constructed according to myinvention,

so as to discharge the load, and of closing 'thereby wound up and thelinks 27 and 29 raised. During this operation the shaft is held againstbackward rotation by a pawl 39 (see Fig. 8) which engages with a ratchet120 which is fast on the shaft 36. This A pawl forms part of a lever 41.pivotally se cured to the frame at 101.

The construction of this pawl and the devices immediately relatedthereto is shown in detail in Fig. 8. The lerer 41 is pivoted to the endof the car body at 101, and may be locked in the position shown in thedrawing by means of the pin 130, which passes through a perforation inthe saidlever 41 and a corresponding perforation in the member 132.

41 by means of a sleeve 109, rigidly mounted T on the said rod .41.`Also pivoted at 101 is an L-shaped lever 110, having its movementlimited by the guide 111, and provided at one end with a notch adaptedto be engaged by the ltooth 135. To the other end of this lever 110 ispivoted the pawl 39, as shown at 112. a portionof said pawl near theouter maan ai until it strikes against the stop 133. The lever` 102 isthen moved against the pressure of the spring 103, thus disengaging thetooth 135 from the recess in the lever 110. AThe pressure of the ratchetwheel against the toe of the pawl 39 forces the same upward, the lowerend of the lever 110 moving to its extreme left hand position, thusallowing the free rotation of the ratchet 120.

When air is used for operating the mechanism, it is applied by means ofthe devices' is intended to operate a pinion 47 being guided or steadiedby the roller.90 (best shown in Fig. 7, which is a side elevation,lookingI from the left, of the portion of Fig. 2 just above the cylinder49) the said pinion 47 being fast on a windlas's-shaft 91 which alsobears winding drums 92. Attached to these drums and adapted to be woundup thereon are chains 93 (see Fig. 2) the other ends of which aresecured to the winding drums 94 on the shaft 36. (See Figs. l and 7.)Since this same shaft 36 also bears the winding 'drums 37 and upon whichare wound the chains 31', unwinding the chains 31 on the drums 37 windsup the chains 93 on the drums 94 and vice-versa. A' guide roller 54 (seeFigs. 9 and 10) is provided for directing and steadying the movement ofthe piston.48. On the piston rod 48, just below the guide roller 54 buton the forward side of the pistonrod, is a lug `or toe 50, whichoperates the bar 51 when the piston is raised. Connected to the ends of`this bar 5l are links 57 (see Figs. 9 and l0) which are connected tothe forward ends of bell-crank levers 59, the other ends of which areoperatively connected to the channel-irons 25`heretofore described.

The operation of my invention is as follows: Suppose that it is desiredto dump by hand, and' in the middle of the track, between the rails; themembers 3 3 are swung into the positions shown in Fig. 5, and the levers(which normally when the car is closed lie in the position' shown inFig. 3) are swung upward'. The levers' 65 are then operated, which drawsthe channel-irons 25 out and permits the swinging side members 19 and 20to drop into the position shown in Figi 5 and thus-permit the load todischarge. After the car has been emptied of its contents. cranks areapplied to thesquare ends of the shaft 36 and mi by rotating the' 'saamthe chains l31 are wound up and the swinging members are replaced intothe position shown in Figs. 2 and 3, whereupon the levers 7 0 areelevated and secured by the catches 71.

Suppose it is desired to dump outside of the track, on both sides. lnthat case the swingingmembers 33 are placed in position shown in Figs. 3and 4, and the channelirons 25 withdrawn as before, whereupon themembers 19 and 20 swing outward to the full extent, as shown in Fig. 4,and are held there by the operation of the block against the links 27and 29. After the discharge the swinging members 19 are replaced asbefore described, the levers 70 being first elevated so as to withdrawthe blocks 75 and permit the links 27 and 29 to be moved, and thechannel-irons 25 are pushed back into their supporting position.

If it be desired to dump on one side of -the track only, the operationis the same,

eXcept that the parts on the corresponding side of the car only areoperated. i

When the dumping is to be done by power, the opening and closing of thesides are performed by admitting air to the cylinder 49. If air isadmitted below the piston, the rod 48 is moved upward, and by -means ofits rack operates the pinion 47 which unwinds the chains 93 from thedrums 92, and allows the same to be wound up upon the drums 94, thusallowing the chains 31 to unwind from the drums 37. The levers 70 mustof course first be released. To elevate the sides, air is admitted abovethe piston, moving the rod and rack downward, and operating the parts inthe contrary manner to that just described. The determination of theload to the middle or one or both sides of the' track as the case maybeis accomplished in substantially the same way as is done when the loadis dumped by hand, as has been already de:4

scribed. i i
